Our Verdict

Lange's RX LV earned our all-rounder award by providing a comfortable fit that still delivered on strength and performance. Our testers were pleasantly surprised by the responsiveness of the Lange RX LV, as it brought snappy turns and happy feet throughout the testing period. Lange also hit the mark on designing an approachable boot that would suit a wide range of skiers and skiing abilities. The RX LV performs with precision and remains a reliable option for all-mountain pursuits.


The latest version of the RX 110 LV has had some slight updates from the version that we tested. The newest style, pictured above, has an updated tongue and buckle design and some updated graphics. The rest of the boot, including the shell and the liner, remains unchanged from the model we tested.

Our Analysis and Test Results

The Lange RX LV earns one of our top awards for its all-around fit, comfort, and performance. One of our favorite boots for its approachable nature and snappy downhill capabilities, the Lange RX LV is a boot for ladies who want a responsive, anywhere, anytime boot. While it has one of the softer flexes in the test group, it managed to ski well on everything from hardpack groomers to soft powder to steeps and bumps. Our only grapple with the boot was a comparatively underwhelming out-of-the-box fit thanks to the Dual 3D Liner Pro's slightly shorter and wider toe box. With a stiffer flex and a better-adjusted fit, this may have won our Editors' Choice Award.

Performance Comparison

The RX 110 LV still delivers a responsive performance, even though we felt like it was softer than a 110 flex. With a little more finesse and less of a "bull in a china shop" technique, this boot will deliver the goods to a more intermediate skier.

Performance


Unlike the stiffer boots in our lineup, the Lange RX LV truly moves with you, not against you. This was one of the easiest boots to lean into and over to capture its full downhill potential, while stiffer race-style constructions required strong legs and full-body engagement. For this reason, we didn't feel as powerful on long-winded, top to bottom groomer laps but felt it was easy to jump into bumps or tight terrain. The boot was stable yet energetic and required minimal effort to activate such a responsive transfer of power. Transferring power from the front of the boot to the tip of the ski is seamless.


Lange constructed this boot with a thicker, more rigid plastic than previous models. The Dual Core Shell is designed with stiffer plastic around the heel, spine, and lower foot areas to retain stiffness and softer plastic around the front/top of the foot to enhance response time and increase comfort.

If you are used to a stiffer boot, this may not be the one for you. The 12-degree forward lean paired with a 4-degree ramp angle sets the skier up with a more relaxed, natural upright stance. Luckily, the forward lean is adjustable; otherwise, this may not be comfortable for more aggressive skiers. Unfortunately, our heavier (150 pounds+) and taller testers felt like the boot collapsed more quickly than boots with a higher flex rating. For these testers, the boot felt more like a mid-volume, lower flex boot. For those with longer legs or longer shins, the lower cuff height may feel short and limit the overall control you have over your skis.

Despite these shortcomings, the forgiving flex on the Lange RX LV will still appeal to a wide range of skiers that explore the mountain no matter the forecast. We skied both steep off-piste runs and groomed cruisers with confidence, and ultimately the testers gave the RX LV a solid thumbs up. Overall, this boot is packed with performance and, now, comfort.

Comfort


The new and improved Lange RX LV liner is made with a hearty Thinsulate layer that keeps the feet nice and toasty. It remained dry after clunking around in sloppy spring slush puddles. Once wet, our toes were a bit cold for some of our testers with narrow forefeet due to the slightly roomier fit of the toe box. This boot retained a respectable amount of heat, though it didn't necessarily stand out as warmer than other boots we tested.


The boot was somewhat clunky in regards to thickness. It comes with alpine soles as the stock option but provides Gripwalk soles as a replacement for those looking for a more comfortable walk to the car. All in all, the entry and exit into this boot were seamless. Our feet literally slipped in and out thanks to the plush Thinsulate liner.

Fit


This year we tried out the LV, or low volume, version of the RX, which at 97 millimeters wide, measures slightly narrower than most "low volume" boots with a 98-millimeter last. Despite a narrow construction, our first impression was that the boot did not have as snug of a fit as expected. Ironically, this didn't make a notable difference in performance. The toe box was a more obvious defect in the fit, where the liner seemed to come up a bit short, and the toes had slightly more wiggle room. Once again, this didn't seem to impact performance but made for some discomfort while standing straight up in the lift lines or walking to and from the car.


Thankfully the latest version of this boot made comfort a high priority. Lange acknowledged the change in fit from previous years' models by mentioning the last is noticeably more relaxed in width and instep height. The new design retained the precise heel pocket from past models, hugging your Achilles and locking your heel into place. This is a welcomed fit after experiencing heel lift in some of the competition's roomier heel pockets. The Shin Control liner contains a soft, plush tongue that adapts perfectly to the lower leg. Lange designed this liner to increase shin support while alleviating common pressure points and shin sensitivity, thus improving comfort and performance. The asymmetrical tongue constructions have generally provided a more comfortable fit with fewer pinch points.

Compared to the rest of the lineup, the Lange RX LV has a beefier build. Some felt it was one of the clunkier options in the group, though it did not jeopardize functionality.

Features & Customization


The Lange RX LV includes a fully customizable thermo-moldable liner with two types of high-density foam. As always, we recommend taking your new boot straight to your local boot fitter to maximize comfort and fit. The forward lean is set at 12 degrees and is adjustable up to 16 degrees. This setup is slightly more relaxed than the industry average of 13 to 18 degrees. Feel free to ask the boot fitter for recommendations on adjustments.


The buckles are micro-adjustable, as most are. They flaunt a unique Ergogrip design that adds extra aluminum to the tips of the buckle to make grabbing and buckling easier. The 40-millimeter velcro power strap works well but is not quite as thick as other bootstraps in the lineup. Luckily, it is replaceable for those who can't get rid of their beloved Booster straps.

Value


Lange has long upheld their reputation for delivering products that deliver precision and performance. It seems that they've outdone themselves and blended these traits with comfort. The Lange RX LV retails in the medium to high price range of our test lineup, though this seems to be a solid bang for your buck type of boot. If the RX LV meets all your criteria, give it a try, we think you'll like it as much as we did.

Conclusion


The Lange RX LV can do it all for the intermediate to advanced skier, with the caveat that it's a little soft for our heavier and taller framed testers or anyone who would rate themselves as an expert. With a shorter cuff than the alternative high-performing race-style models, the Lange RX LV proved to be a better fit for most shorter, smaller-framed skiers.
